Do you have a link to a study that has better science in it than the IPCC report? Is there a such a study? If not, maybe, just maybe, the climate scientist are right and the ever increasing CO2 is the culprit. Maybe.

Here's one - http://www.drroyspencer.com/2019/08/july-2019-was-not-the-wa...

So one guy? An Intelligent Design proponent whose work is partly funded by the coal industry? Yeah, that puts a little damper on anything he's writing, doesn't it?

And this isn't even getting close to the IPCC report. It's not even in the same league. I'm not sure you even know what the IPCC is, who is involved and what its results are, am I right?

The cost to mitigate global warming is much less than the cost that humanity will bear if it isn't mitigated. This is often argued as binary: 0) doing something will destroy the economy, 1) doing nothing will destroy the world. But in reality, there is quite a bit that can be done that doesn't cost that much. The innovators require the price signal. Externalities need to be internalized before the market can solve th…

For starters, lets feed the cows some seaweed. IMO technology is very rapidly evolving which will drastically reduce emissions with very little negative trade-offs, and in fact, do so in an economically competitive fashion. The EV cars don’t just emit nothing, they are also better cars in almost every respect. The seaweed cows don’t just not fart methane, they grow fatter for less feed. The solar power isn’t just gre…

The reduction of emissions due to efficiency does not counterbalance the increase of emissions. I'll take cars as an example: today's engines are really more efficient than engines in the 60s but cars are bigger, there are more cars per persons, there are more people. EV are a solution, but their are not 0 emissions, the construction of course emit some carbon, the delivery of cars around the world too. If they are used in china they probably will be using coal electricity. Building, delivering and powering a EV for everyone that use thermal vehicle and an increasing number of people that buy a first car won't reduce the carbon footprint. The reduction of emissions won't happen without scaling back the economy and/or the population.

So, are you saying this is the hottest July in 4.5 billion years, or that this is the hottest July in 150 years, which is 0.00003% of the earth's history? Two fairly different claims.

https://en.wikipedia.org/wiki/List_of_periods_and_events_in_... You may find this information useful.

Not especially. A bunch of data and theories with very loose granularity. Plus, it seems temperatures were hotter today than in the past. Does this cause problems for the current claim? Why, why not?

Drill in to the links instead of dismissing them with a handwave, and you'll find what you're looking for.

For example, here's a list of known climatic forcing events:

https://en.wikipedia.org/wiki/Category:Events_that_forced_th...

They help us verify models, and see what sort changes one can expect when disruptions to the system happen.

To answer your specific question:

It's the rate of change that's the problem. What used to take thousands of years is now taking decades. If that doesn't seem like a big deal, think of the difference between stopping a car with normal braking action vs. crashing in to a brick wall. In both cases, the car changes its velocity by the same amount. It's the rate of change that causes the difference in trauma levels.

I thought there were events in the past like comets striking the earth that disrupted the global climate in days or perhaps even hours. Obviously, earth has more than recovered from a comet strike. It's hard to believe that what we are doing could be worse.

Of course, I'm not saying I want to be here for a comet strike! But, we shouldn't pretend it's the earth's health we are concerned about, since the earth apparently can weather much, much worse than anything we can throw at it. It is our own human civilization we are worried about. And according to the climate models I see thrown around we have a century or so of slowly creeping sea levels to avoid. That seems pretty doable given all the things we humans have done in the past couple decades alone.

Earth did, after millions of years and a mass extinction. I'd rather not have that happen to the biosphere if it is something we can control.

Some food for thought: Earth is already well on the backside of how much longer it will be able to support life. (https://en.wikipedia.org/wiki/Future_of_Earth for more details) Stopping damage now is the better option that thinking "Eh, things will recover in geologic time." Geologic time is running out.

tl;dr- Earth is ~4.5 billion years old. Solar output increases by ~1% every 110 million years. There are ~500 million years left before long-term processes make Earth a hostile place for life.

Right, so it's not earth we are concerned about, b/c earth is doomed anyways. It's human welfare we are concerned about, and that should be how the debate is framed. In what way does climate change possibly impact human welfare and what is the most practical way to address those impacts? Not a blanket 'climate change is bad so stop all CO2 production!'

The IPCC report goes in to what the actionable items are in great depth. If you're interested in what we know, and what the best steps are to do, it should be your starting point.
